Same question as to Stefano the other day: What use if iommu.o when both
config options are off?

The answer has not changed here. So I will just copy his answer:

"Things like iommu_domain_init are called unconditionally from ARM code
at the moment, it is not quite possible to skip compilation today. Also,
it is small, so it is not worth it I think."

Cheers,


Jan
